Description
- The present invention relates to a hinge structure and in particular to a variable-torque hinge structure with auto-locking and easy opening-firm closing functions.
- Consumer electronics with flip covers, such as portable computer, electronic dictionary, portable audio/video player, flip mobile phone, generally have a main body on the bottom, which is pivotally connected with the cover to body on the top, such that the cover body may swing open or close with respect to the main body. Consequently, the rotating axle is key to the quality of the products described above.
- To prevent the main body and the cover of the 3C electronic products described above from swinging open arbitrarily, at least a sliding or pressing switch is provided at the respective limit of the movement angle such that the switch may be used to fold them together to close down during swinging close. However for this type of automatic locking mechanism, the rotating shaft structure with automatic locking mechanism has to be provided with corresponding holes and locking elements, leading to an increase in the complexity for assembly and the manufacturing cost. It is therefore necessary to provide a new design to overcome the drawbacks described above.
- Consequently, to provide the cover body with an auto-locking function with respect to the main body, it is a conventional approach to dispose a cam member in the hinge structure, such that the protruded portion of a rotation member of the cam member is engaged into an indented portion to mate together and thus to achieve the desired auto-locking function. Therefore, when the cover is being flipped open through the cam member, a user has to provide a force to render the protruded portion to move out the indented portion thereby achieving a hinge structure with the “easy opening and firm closing” function. It is not a user-friendly design because a rather large force has to be exerted to flip open the cover body. As a result, the flipping opening motion usually requires the user to press down the main body with the other hand; otherwise, the main body will be lift upward along with the cover body, thereby causing inconvenience. Therefore it is an urgent task to provide a variable torque mechanism with “easy opening and firm closing” characteristic when the cover body is being opening up with respective to the main body.
- In view of the foregoing shortcomings of the prior art, the inventor of the present invention based on years of experience in the related industry hopes to improve the user-unfriendly design of “easy opening and firm closing” for conventional auto-locking hinge structure. The aim is to include a variable torque mechanism to a hinge structure and thereby when the hinge structure according is being flipped open, the torque required for “firm opening and easy closing” is dispersed and thus a small force is sufficient to flip open the cover without lifting up the main body. After numerous experiments and tests, a hinge structure according to the present invention has been achieved.
- In order to accomplish the object described above, the present invention is to provide a hinge structure, comprising a pivot having a linking portion disposed with a circular axle axially and a smaller axle extending from the center of the front end of the shaft; a main frame having a connection portion which is formed axially to have a bush-like tube spring below for the insertion of the shaft, the tube spring being positioned to have a gap with the connection portion and one end of the wall of the tube spring being formed to have an notch; a cam member having a rotation part and fixed part between which is disposed with concurrent protruded and indented portions and which are installed inside the tube spring for the insertion of the axle, the rotation part being axially disposed with a protruded tenon which is connected with the notch of the tube spring, and the fixed part being secured with the axle; and at least a resilient member insertingly connected with the axle and secured with the connection segment of the axle by an end enclosure, which presses and constrains the aforementioned parts.
- Another object of the present invention is to provide a hinge structure wherein the linking portion of the pivot is formed to have at least a linking hole and the connection portion of the main frame is formed to have at least a connection hole.
- Yet another of the present invention is to provide a hinge structure wherein the connection portion extends to form a linking plate from whose end a bush-like tube spring is formed thereon and a gap is maintained between the tube spring and the linking plate.
- Still yet another object of the present invention is to provide a hinge structure, wherein concurrent protruded portions and indented portions are alternately disposed at the inner and outer brim edges of the connecting surfaces of the rotation part and the fixed part and are engaged together.
- Still another object of the present invention is to provide a hinge structure, wherein the resilient member is a disc spring, wave spring or spring.
- Still yet another object of the present invention is to provide a hinge structure, wherein a spacer is disposed between the end enclosure and resilient member and is formed on its surface to have a multiple of oil holes to receive lubricating oil.
- Still yet another object of the present invention is to provide a hinge structure, wherein a stop rim is protrudingly disposed at the wall of one end of the tube spring and a fan-shape limit stop is protrudingly disposed at the rear end of the shaft, such that the two ends of the stop rim and the limit stop can limit the angle of opening and closing movement.

Between thetube spring 23 and the linkingplate 22 lies agap 231 which provides a radially resilience for the insertion of theshaft 12 so as to exert a friction torque. Further, to secure therotation part 31 of thecam member 3, the wall of the front end of thetube spring 23 is formed to have a notch. - The
cam member 3 is received in thetube spring 23 and comprises arotation part 31 and afixed part 32 between which is disposed with a concurrent interference structure; for example, the inner and outer brim edges of two connecting surfaces are concurrently disposed with alternate interference structures, respectively, which are then engaged together.
